“It was only when I met my friend who is trans that I realised it was OK not to fit into the boxes that are given to you.

“I moved out of my mum’s house when about 15 — it was after my parents split up and her new boyfriend moved in.

“I cut my hair off as soon as I had a choice. I didn’t want it long.

“I stopped wearing dresses and girly things.”

Talking about his first sexual experiences, Hayden said he felt “confused” about his feelings and had school crushes on both boys and girls. He said: “I went out with a few people but I didn’t fancy either sex more than another.

Thomas, of Phoenix, Arizona, US, went on to have three kids using donor sperm.

Canadian Trevor MacDonald, 31, revealed last year how he breast-fed his first child in a men’s toilet in a restaurant. He said: “It was this weird scenario.”

It's baby I fear for the most - by Deidre Sanders, Sun Agony Aunt

I CAN understand how Hayden feels he was pressured into having a baby before he was ready, but the person I am so worried for in all this is the baby he is expecting.

Hayden’s childhood must have been insecure and lacking a constant and caring father-figure. He was a troubled boy who was vulnerable to any person or influence who made him feel special. It’s telling that Hayden’s overwhelming drive now is to have a child rather than a relationship. It’s how girls who have had an unhappy family background often react — imagining it will create the happy family life they missed out on. But it often doesn’t work out like that. Hayden says his mum is going to help him raise his baby, although she does not recognise him as a man. Imagine the confusing messages the baby is going to get. I just hope Hayden gets lots of understanding and informed support.

It's twice as tough - by Carol Cooper, Sun Doctor

BEING pregnant can be tough, especially when you’re not ready for it.

But Hayden has the added challenge of transitioning to become male. This involves social and psychological preparation and biological changes that often include drugs and surgery. Hayden is in the centre of two utterly opposing changes. It’s no surprise he’s conflicted and angry. I hope for his child’s sake he comes to terms with the pregnancy and the responsibilities ahead.
